Nutone Range vent hood motor is loud or noisy
A noisy NuTone range vent hood usually has a worn exhaust fan motor, fan motor, blower motor, or vent fan motor bearing. With the power disconnected, check the motor shaft by gently wiggling it back and forth. The shaft should not move, even slightly. If it does, the bearings are worn and can cause oven fan noise, range vent hood humming, scraping, or other unusual sounds. Some older, larger NuTone motors have oil spouts. Adding oil to the motor bearings may help the fan turn freely, but replace the motor if lubrication does not stop the noise or the motor cannot be lubricated. If the motor shaft is firm, inspect the blower wheel next. A worn or loose blower wheel can slip on the shaft and scrape the fan housing. The fan blade can cause the same problem if it is loose, damaged, or worn. Tighten the wheel or blade if appropriate, and replace it if it remains loose. Enter your NuTone range vent hood model number to find the exact replacement motor, blower wheel, or fan blade for your specific hood.
01 - Nutone Range Vent Hood Exhaust Fan Motor
The exhaust fan motor bearings might be worn out. To determine if the motor bearings are worn out, try wiggling the motor shaft back and forth. The motor shaft should not move at all. If the motor shaft moves even by a slight amount, the motor bearings are worn out. Some older, larger motors have oil spouts. If your motor has oil spouts, try adding oil to the motor bearings to get the fan to turn freely. If lubricating the motor bearings does not solve the problem, or if the motor can’t be lubricated, replace the exhaust fan motor.
